Question Unable to control case fans

[Zandernak]

Hello everyone. I am unable to control case fans via both Smartfan and BIOS. They are working normal, RGB LED works fine as well. I just can't find a way to control their speed/noise. BIOS shows me their RPM but when I change them from normal to silent nothing happens. Right now they are spinning at around 1300 RPM which is very loud (and there are 3 of them). I can control my CPU fan in BIOS normally.

Specs:
CASE: Sharkoon Night Shark
MBO: Gigabyte Z370P D3
CPU: Intel Core i5 9600K
CPU Cooling: Cooler Master Hyper 212X

the only way is with a fan controller 20-30 pounds

Okay, I figured it out. I connected fans to MOLEX and to 3-pin cable to MBO at the same time. Now I have unplugged them from MOLEX and left them connected to MBO only via 3-pin cable and everything works perfectly. I can adjust their speeds as I want, they were running at max speed before (too much power?). Thank you anyway.

Since I am new here I don't know how to close thread and/or mark it as solved.
